Abstract
Straintronics of two-dimensional (2D) materials is a new research area in condensed matter physics for studying 2D materials under strain. Anisotropic strained graphene does not seem to preserve the polarization of the incident light. This suggests intriguing possibilities for developing surface plasmon resonances (SPRs) in graphene-based optoelectronics. In this work, we investigate the SPR properties of a graphene–prism coupling structure under a relatively small anisotropic strain. We demonstrate that, for an incident linearly polarized light in the strained graphene–prism coupling structure, anisotropic SPRs would emerge along with specific strain directions.
